Tournedos Rossini is a French steak dish consisting of a beef tournedos, pan-fried in butter, served on a crouton, and topped with a hot slice of fresh whole foie gras briefly pan-fried at the last minute. The dish is garnished with slices of black truffle and finished with a Madeira demi-glace sauce. It is named after 19th-century composer Gioachino Rossini.
